SPECIFICATION fonning part of Letters Patent No. 677,434, dated J'uly 2, 1901. Application filed April 12, 1901- serial No. 55,484. (No model.)

To all whom it may concern:

Be it known that I, HEINRICH BRINKMANN, a citizen of the Empire of Germany, residing at Munich, in the Empire of Germany, have invented certain new and useful Improvementsin Thrust-Bearings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to thrust-bearings for the propeller-shafts of vessels, or for other revolving shafts that are subjected to pressure in an axial direction.

The object of my invention is to provide improved means for permitting the bearings to move, as it were, on a universal joint in order to compensate for any unequal wear in the bearing-surfaces and also to compensate for any slight lateral vibration or movement of the shaft.

WVith this object in View a thrust-bearing embodying my invention consists in a shaft provided wit-h a disk secured transversely thereto, in combination with a head or heads containing bearings arranged to engage the disk and journaled in boxes and means for adjusting such boxes axially of the. shaft.

Myinvention also involves the combination, with the above, of means for permitting the head orheads to swing about an axis perpendicular to the journals of the head; and my invention further comprises such details of construction and arrangements, either separately or in combination, as will be hereinafter particularlydescribed and then pointed out in the claims.

In the accompanying drawings, representing mechanism embodying my invention in my preferred form of construction and ar-' rangement, Figure 1 represents a plan view, certain parts being shown in section. Fig. 2 is an elevation of the mechanism shown in Fig. 1, certain parts being shown in section. Fig. 3 shows in plan a modification of the mechanism set forth in Fig. 1, certain parts being shown in section. Fig. 4 represents an elevation of the mechanism shown in Fig. 3. Fig. 5 shows in elevation another modification of my invention. Fig. 6 is a plan view of the modification shown in Fig. 5, certain parts being shown in section. Fig. 7 represents in plan view another modification, certain parts being shown in section. Fig. 8 is an elevation of the modification shown in Fig. 7, certain parts being shown in section.

Referring now particularly to Figs. 1 and 2, the reference-letter a indicates a shaft on which is secured transversely a disk I), having on each of its opposite faces a bearing ring or washer 71. A bearing-head c has journals jj secured thereto at the extremities of a diameter and contains a series of antifriction devices, such as rollers d, pivotally secured thereto. A pair of stationary frames 2' are arranged parallel with each other, and each contains a longitudinal slot In each of these slots is arranged to slide a journalbox 9, that serves. to support, respectively, the j ournalsj j of the head 6. The said frames and head are so located that the series of rollers d engage the disk I) at its friction-ring h. A ringf has journals 0 0 secured thereto at the ends of a diameter, which journals engage, respectively, the boxes n n, that are arranged to slide in the said slots 7." z" of the frames 2' 2'. The said ringfhas a cylindrical face f, which ring is so located that the said cylindrical face engages the face 6 of the head 6 on a line that is transverse to the axis of the journals 0 and also transverse to the axis of the shaft Cb. The movement of the said boxes n n in the slots 11 z" is limited by a pair of adjusting-screws k k, which preferably have jam-nuts k to secure them when properly adjusted. The head 6 may also have an antifriction-ring h, arranged to engage the rollers d. The opposite face of the disk I) has a bearing arrangement that is a duplicate of the parts hereinbefore described, but which are arranged in a reverse order from these described parts. The function of these duplicate parts is to receive the thrust of the shaft in the opposite direction from that which is received by the above-described parts. The operation of this mechanism is as follows: If there is an unequal wear in the ring h or the ring h either above or below the shaft, the head Q will automatically oscillate on the journal j, thus causing pressure between the rollers and the ring to be distributed among the series and not confined to a few of them, as would be the casewere this head not so adjustable. naled ring f can so oscillate and assist in compensating for the said wear of the ring h above or below the axis; but should there be an unequal wear of the ring it at either The said journally in the slots i, as

side of the axis of the shaft the head 6 will automatically oscillate on a vertical axis in virtue of the bearing of the cylindrical face of the ringf on the side e of the head e in a vertical line. During said oscillation the boxes g of the journal j will slide longitudiwill be readily underof the bearing parts on the opposite side of the disk I) will be identical with that just described. The adjustingscrews 70 permit the head 0 to be moved to and from the bearing-disk b, as desired. It will also be readily understood that any lateral movement or vibration of the shaft a will cause a corresponding distortion of the bearing-disk b, which will be automatically compensated for by the double oscillation of the head 6, as above described.

Referring now particularly to Figs. 3 and 4, the head 6 is mounted by journals j in boxes g, that slide in slots 0; in the frame i, similar to the arrangement of the above-described box e. The box e contains a series of antifriction devices, such as rollers cl; but these rollers do not bear on the box 6, as in the former case. A ring a is mounted in the box 6 and serves as a bearing for the said rollers 61. A pair of pins J J are secured to the head e at diametrically opposite points in a vertical line and contact with the rear face of the said ring a The opposite face of the disk I) in this modification also has a duplication of the parts just described, but which are arranged in a reverse order. In the operation of this modification the head 6 oscillates on the journals jj, as in the form shown in Fig. 1; but in order to compensate for wear on the bearing-ring h on either side of the shafta said ring 6 oscillates about a vertical axis in virtue of its being supported on its rear face by the vertically-alined pins J. This modification has the adjustingscrews k, that serve the same function as in the form shown in Fig. 1. V

In Figs. 5 and 6 is shown another modification, in which the bearing-disk b has the bearing-head e, containing the antifriction stood. The operation rollers cl, as hereinbefore described and shown with reference to Figs. 1 and 2. This head (2 also has the journals jj, engaging boxes 9 9, that slide in slots t" in frames 1 similar to those shown in Fig. 1. A ring f has diametrically opposite extensions f towhich are secured, respectively, pins 19 p, engaging apertures g in the said boxes g. The rear. face of this ring f has at places that are ninety degrees distant from the said extensions f projections f that engage, respectively, adjustingscrews 79 k, mounted in a ring 5, that is secured to the said frames. The opposing face of the disk Z) in this modification has a duplication of the bearing parts just described, but which are arranged in reverse order. In the operation of this modification the swinging head e performs the same function as in the form shown in Fig. 1-that is, it compensates forwear in the frictiont. In the operation of this last modification the support of the ring 7r either above or below the axis a. When there is any wear in the friction-ring on either side of the axis, the ring f swinging about a vertical axis by reason of its vertically-alined supports f f, permits the box c to compensate for this wear.

Another modification of my invention is set forth in Figs. 7 and 8, in which the disk I) has secured toits opposite faces rings or cones c c, in proximity to which are arranged, respectively, bearing-cups c c, which cups and cones form a raceway in which is located a series of balls (1. A pair of rings 0", each having a cylindrical face on, are arranged to contact with the rear face 0 of the cups 0 c on a vertical line. The rings'rh ave journals r secured thereto at the extremities of a horizontal diameter, which journals engage boxes t, arranged to slide in the slots 'Li in the frames cups 0 c by their cylindrical faces permits the oscillation of the same about a vertical axis, and thus automatically compensates for wear on either the cups or cones on either side of the shaft on 'Any wear of the cups or coneseither above or below the shaft is automatically compensated for by reason of the oscillation of the rings 0' about their horizontal axes on the journals r Adjusting-screws 7:, in this modification permit of movement of the parts in an axial direction, as will be readily understood from the foregoing.
